A Comprehensive Review on Liquid-Liquid Extraction Based Systems in Treatment of Textile Wastewater

Objectives: To present an overview on various extraction systems used in treatment of textile wastewater. Methods: Google Scholar database was used to collect literature on liquid-liquid extraction systems in treatment of textile wastewater between 2000 and 2021. Findings: Even though a variety of methods are available for treatment of textile wastewater, certain methods remain neglected without much attention. One such method is liquid-liquid extraction-based systems. Hence, the manuscript presented an overview on applications of liquid-liquid extraction systems in treatment of textile wastewater. Novelty: Wastewater treatment is most important in today’s life because of excess urbanization and industrialization. In developing countries, tonnes of wastewater is discharged without prior treatment. Hence, liquidliquid extraction could be a novel method for treatment of textile wastewater.
